Wide Ruled Spiral Bound Notebook
Wide Ruled Spiral Bound Notebook is generally made of environmentally-friendly kraft paper cover. Kraft paper is high-strength and durable, making it the most basic requirement of environmental protection cover. The inner core uses high quality paper.
After the spiral coil is locked, the page cannot be added unless the coil is removed. The cost of double-coil binding is higher than that of a single coil. Of course, the binding effect is better and more durable.
With a two-coil bound book, you can completely flatten any page when reading, making it easy to read and query.
Books with a thickness of 30mm, such as tool books, technical manuals, recipes (recipes), VIS manuals, and architectural drawings, are best suited for this type of binding.
